To clLwhom-it may concern: v

Be itknown that '1, Jamns '1. ANDREW, a citizen of the United States,r'esidin at Montgomery, in the county of Montgomery and State ofAlabama, have invented-certain new and. useful Improvements in.

Safety Appliances ior'Railroad-Cars, and I do hereby ing fan improvementupon, my former patent No. 844,288 dated February 12, 1907, and myformer apdeclare the following to be afull, clear, and exact de-'scription of the invention, such as will enable others skilled in theart to which it use the same. Y

My invention relates to improvements in safety devices for, railroadcars, and the object'of my invention is toprovide means'wherebyderailment of a train, with the injurious effects resulting therefrom,shall be rendered practicallyv impossible, this application beplication', Serial No. 349,727dated December 27, 1906.

My. invention is applicable not only to railroad cars, but also toelectric cars of all descriptions, and to locomotives. I w I With thisobject in view, my invention consists in the construction andcombinations of partsas hereinafter described and claimed. V

In the accompanying'drawings; Figure -l is a side View of a portion oiapassenger truck showing my intrack.

Fig. 4 is across section, Tonanenlarged scale, taken on the line 4- 4 of Fig. 3, and Fig. '5 isaperspective view of one of the 'a represents the truck side frame, bthe pedestalfc' theequalizer bar, d one of the supportin'gsprings, e thejournal box and f a brace, all ofthese .parts being of the ordinaryconstruction. l I Firmlybolted to the equalizer bar is a'frame g whichcarries the shoe h; The outer shoe of each pair is pivoted on a frame,such as g; and this frame is firmly secured to the journal boir by Ushaped hangers :1 secured at the ends by bolts 7', sothat theequalizerbar,

shoe irame jshoe' and journal box are all connected together and, movetogether. Bolts k pass through the shoe frame gaudloosely throughthelower of the N ear each end of each of the shoes is mounteda rolleris, provided withianenlarged rimpl, which is sup: ported in bearings atthe end of theshoe, as shown in Figs. 3 4, friction balls m beinglocated between the axle 'end of the roller a dfnds of the: shoe, sothat said rollers move with the gre'atest ease. l

Springs 11 and q are connected'to the roller and to the equalizer barand brace f respectively, which springs normally 'keep'the shoe hsuspended in its proper position as shown in Fig. 1. Q

I .The inner shoe r of each pair issubstantially similar "inconstruction to the outer shoe but is suppor ed directly on the caraxl'e t, the sleeve 8 preventing its of the hub of the car wheelprevents its movement in the other. direction longitudinally of theaxle.

The shoe 1" is supported on the axle t by means of a divided hearing tand the shoe is cut away as shown in dotted lines in Fig. 3, for thereception of oily waste for the purpose of lubrication 'In otherrespects the inner shoe 1' is the same as the outer shoe'h.

. To limit the upward movement of the shoe r in either direction I have.provided downwardly extending brackets a'c'and .y attached to the beam 2forming a part of the car frame-work.

'ent application are the means for suspending the shoes and theprovision of anti-friction rollers in each shoe. Show shields 1 areprovided as inmy'application 'Serial'No. 349,727 to prevent theshoe-from being operated by snow or other hbstructions along the track..The movement of the shoes is-adapted to set the brakes as described inmy former patent No. 844,228.

Having thus described my invention, I claim:-

' 1. In a safety appliance for cars and locomotives, the combination oftrucks. and means carried thereby for automatically lilting said trucksand applying the braking notion in case otnccldent, said means includingspring each end '0! said shoes, substantially as described.

-2. In}! satety appliance for cars and locomotives the comhlnatlon oftrucks having side beams, pedestals and equalizers, of a pair orspring-controlled shoes for each wheel, on either side thereof, saidshoes being each pro- "vlded wlthanti-friction rollers near their ends,substantially, as descrlbed.

3. In a' fety appliance for cars and locomotives the combination of thecal" frame, pe(lestals, equalizer bars, caraxle undfjou-rnal-box with apair of shoes for each wheel each shoe being provided, withanti-friction rollers hear each end,'one of said shoes being mounted onthe car axle inside the car Wheel, and a shoe frame bolted to theequalizer bar and carrying the other of said shoes, andhangerspassingthrough said shoe frameand around said journal )box, substantially asdescribed.

In testlmonywhereof, I ulfix my signature, in presence o! two witnesses.
